TANK FOR. STORING ACETYLNE GAS.

Specication of Letters Patent. Application filed August 27, 1906;

Patented sept. 7, 1909, Serial No. 332,091.

To all whom it 'mayconcem: l

Be it known that I, 'PERCY C. AVERY, a citizen of the United States, residing at Milwaukee, consin, have invented a certain new and useful Improvement in Tanks for Storlng Acetylene- Gas, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the accompanying drawings, which form apart of this specification.

My inventionrelates in'general to tanks for storing gas, and more particularly to portable tanks for containing acetylene gas under pressure. v

convenient and eiiicient method of supplying automobiles and other vehicles with illuminated gas for their lamps, is to charge a portable tank containing an absorbent with gas under pressure, the capacity of the tank being increased by placing therein a solvent of the gas. In order that the tank may be charged with gas without generating a dangerous degree of heat the absorbent should be of such a character as to permit the free passage of the gas to every portion pressure throughout the tank may'increase uniformly.

The primary object of my Iinvention is to provide-an absorbent for a gas storage tank which may be readily inserted through a and which will permit the tank to be charged uniformly with gasthroughout everyortion of its interior, thereby avoiding un uly heating the tank when 1t is-charged.A A furtherobj ect of m vide a pressureagewill automatical invention is to proor gas tanks which y prevent the over-charg- A still' further object' of my invention is to provide a portable gas tank ofthe type coveredby my US. Patent 816,059, granted March 27,1906, which will be simple in -conprising a tank having struction, -inexpensive in manufacture, and eicient in use. g

The embodiment of my invention herein disclosed may be generally'described as coma hole in which an outlet valve'is secured, a plurality of rods of absorbent material of a slze to'pass through thel hole in the tank to' the interior thereof, and afpressure gage having an outlet port closed by ,a plug of such material that it will y its interior.

be blown out when the tank has been charged to a maximum. f

My invention will be more fully described herelnafter with reference to the accompanying drawing in which the same is illustrated as embodied in a convenient and practical form and in which- Figure l is a longitudinal central section; ig. 2 a cross section on line 2-2 Fig. l; Fig. 3 an enlarged detail view of the pressure ga e; Fi l an enlarged cross section of a mo ied' orm of the absorbent rod; and Fig. 5 a 'viewsimilar to Fig.` 4 showing still another form of absorbent rod. Similar reference characters are used to designate similar parts in theseveral gures ofthe drawing. ,l

Reference character A represents a tank which may be of any desired construction but is preferably made of seamless steel.

designates the end wall of the tank whichis preferably counter-sunk to form a chamber in which islocated a pressure gage C.

The pressure gage communicates with the interior of the tank by means of a tube in screw-threaded engagementwith a spud c, the latter being inserted through a hole in the end wall of the tank. The casing of the gage C is provided with a passage c leading to the expansible memberCZ. The passage c extends to the exterior of the casing and is closed by ,a plug C of suitable material, preferably soft metal. l

The end wall E of the tank which 'is referably formed integrally with the cylinriical side walls, is provided with a hole c interiorly screw-threaded. A valve casing F is adaptedto be.4 engaged with the screw-threaded openingfe so that the valve in the casing may control'the passage of gas from thev tank. The valve 'may be of any suitable construction' and is preferably provided with perforated tubular extension kG extending into the body of the tank.

Reference letter D designates a plurality offrods of absorbent material of a cross-section to permit their bei-ngseverally'i serted through the opening e to the interior of the tank. The rods are of a length corresponding to the interior length of the tank so that when the tank has will contain absorbent materiahthroughout The absorbent rods .may be solid as shown in Fig. 2, or may be in the form of tubes,

-been filled with rods ity as shown at D in Fig. 4f

i The rods may also,

if desired, be square in cross-section as shown at D2 in Fig. 5. The rods may be made of any suitable absorbing material such for instance as asbestos, woodpulp, or any other fibrous material.

The manner of charging my improved tank and its operation are as follows: After the tank has been formed and the wall B secured therein the gage C is placed in position within the chamber formed by the end wall and in communication tank. vThe absorbent rods D are then 1nserted in the tank through the screw-threaded o ening e. vThe rods, while substantially fi ling the interior of the tank, have spaces around the individual rods so as to permit the free passage of the gas to every portion of the tank. After the lrods have been inserted in the tank a liquid solvent of the gas, such for instance, as wood-alcohol, carbon-bisuld, petroleum,',chloroform, or acetic acid, is oured through the opening e and is absorbe by the rods. The valve F is then secured within the screw-threaded opening e and gas stored in the tan The gas is introduced under pressure so that-the solvent will become supersaturated. When the tank has been charged with the desired pressure the valve is closed and the tank is ready for use. By opening the valve the gas passes from the tank and as the pressure within the tank decreases the gas lsiliberated by the solvent. l

By forming the absorbent material in the shape of rods the tank may be uniformly charged with the gas as thelrods even when square in cross-section do not lie so close together as to prevent the unobstructed 'passage of the gas to all portions ofthe surfaces of the rods throughout the tank. The danthe passage of the gas to every portion o the tank and the consequent generation of heat is thereby avoided. Another advantage in using rods be inserted through the hole for the valve 1s that the tank may be completed and subjected to the usual hydraulic test before 'the absorbent material is inserted in the tank. The necessity of removing the waterused in testing the tank lby distillation-is consequently rendered unnecessary as thewater may be readily poured from the tank.

a By extending the passage in the casing of the pressure gage to the exterior thereof and closing the same by a plug of suitable material the pressure gage not only records the with the interior of the` of absorbent material which may drical tank pressure in the tank, but also serves to auto'- matically prevent the over-charging of the tank, inasmuch as when a maximum degree of pressure has been attained the plug will be blown from the port and the gas allowed to escape.

From the foregoing description it will be observed that I have invented an improved gas tank containing absorbent material so arranged as to be inserted through the valve-hole inthe tank and of such a character as to permit the free passage of the gas throughout the tank. It will be further observed that I have invented an improved .pressure-gage for gas tanks which automatically prevents the over-charging of the tanks. 4

Having now fully described my invention,l what I claim as new and'desireto secure by Letters Patent is:

1. In an apparatus for storing and delivering gas, the combination with a tank having a comparatively small opening, a plu- 'ality of stiif rods of sorbent material within said tank and of a size to pass through a said opening, and a solvent of the gas to be stored with which said rods are saturated.

2. In `an apparat-us for st-oring and delivering gas, the combination with a tank having a comparatively small opening through a wall thereof, of a valv'e device for controlling the discharge of gas from the tank and having a portion secured in said opening, a plurality of rods of absorbent material within said tank and of a size to opening', and a solvent o stored with which said rods are saturated.

3./ In an apparatus for storing'and deliverling gas, the combination with a cylinpass through said same, one end'wall having a small opening therethrough, for. controlling the` discharge.-
